11 Reef-Safe Sunscreens We Love

When it comes to sunscreen, there's good news and bad news. The good: It can protect us from the sun's harmful UV rays. The bad? It can negatively affect the ocean’s coral reef ecosystem. This is because oxybenzone and octinoxate—key ingredients in many sunscreens—wash off of your body when you’re in the water, causing stress to reefs and the algae that live in their tissues. Eventually, this process can lead to fatal coral bleaching.

So how can you do your part? The answer is pretty simple—know what to look for, and choose your sunscreen wisely. Stick to non-nano mineral sunscreens, and check for natural ingredients. To take out some of the legwork, we rounded up the best reef-safe sunscreens to buy before that trip to the beach.
